Final Thoughts on Redheads and Alcohol Tolerance There's not enough evidence to claim redheads have a higher tolerance to alcohol than other people. However, several social and genetic factors (including the MC1R mutation) may lead to a perception that they have a high tolerance and a predisposition to alcoholism.
Research has shown that people with red hair perceive pain differently than others. They may be more sensitive to certain types of pain and can require higher doses of some pain-killing medications. However, studies suggest that their general pain tolerance may be higher.
Sex Researcher Professor Dr Werner Habermehl said: “The sex lives of women with red hair were clearly more active than those with other hair colour, with more partners and having sex more often than the average. The research shows that the fiery redhead certainly lives up to her reputation.”
It's no secret that their pale skin makes redheads more susceptible to sunburns and skin cancers. However, some research has found a link between redhead DNA and an increased risk of melanoma. Melanoma is a type of skin cancer that begins in melanocytes, cells that produce melanin.
A McGill University study found that redheads could handle more electric shocks than those with different coloured hair. Other research discovered that gingers are better at handling stabbing or sharp pain.
Lifespan: up to 20 years in captivity, 5-10 years in the wild.
According to Health Magazine, redheads can produce their own vitamin D when exposed to low levels of light. 4. You may not need as much pain medication. The gene responsible for red hair (MC1R) also releases a hormone that is similar to endorphins which limit the feeling of pain.
The skin of a redhead is thinner compared to others and is derived from the ectoderm. Teeth enamel is also derived from the ectoderm and thus is thinner than usual. Since the enamel coating is thin, the inner layer of tooth-dentin is more visible and offers a yellowish appearance.
Fun facts about red hair strands
Redheads are less likely to go grey. The pigment in red hair typically fades over time from red to blonde and white, but not grey. Redheads produce more Vitamin D in a shorter amount of time than people with other hair colors.
Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.
Blue- Royal blue or any deep blue makes red hair pop. Blue teal and turquoise hues, as well the ever popular blue denim, are great choices. Even navy works, especially for brighter red hair colors. Navy and ivory is a winning combo for dress and casual clothes.
A study headed by Dr. Edwin Liem at the University of Louisville in Kentucky found that redheads are more sensitive to hot and cold, and are hurt by the cold at temperatures nearly 11 degrees Fahrenheit warmer than others.
Redheads might have less damage/signs of aging
This means that there is a reduced risk of sun damage and early signs of aging in the skin of redheads. This means our skin stays youthful for longer, helping us appear younger.
Colliss Harvey's research found that redheaded individuals have higher levels of vitamin D, which is a source of strength. She asserts that this has been a contributing factor in stereotypes surrounding the foxy minority, which make up 2% of the global population.
Someone with red hair has two copies of the MC1R gene, receiving one from each parent. The gene also carries a certain mutation in most people who have red hair. It's this variant that has been identified as playing a role in why redheads may respond to pain drugs differently than others.
And, while redheads are often stereotyped as stubborn, this isn't necessarily a bad thing. As a matter of fact, that resoluteness is linked to a particular quality of your tresses; red hair doesn't go grey easily, and the strands of hair hang onto the colour for a long time, even if it becomes slightly faded.
Ireland has the highest number of red-haired people per capita in the world, with the percentage of those with red hair at around 10%. Great Britain also has a high percentage of people with red hair.
According to an article by evolutionary biology professor Mark Elgar, PhD, of the University of Melbourne, blue-eyed redheads are the absolute rarest, with 0.17% of the population having that combination of hair and eye color.
“Red hair and blue eyes are both recessive traits which means a person needs to inherit both of the genes for red hair and blue eyes, from both parents. In contrast, brown hair and brown eyes are dominant traits, which is why they are much more prevalent.”
Blue eyed redheads are super rare
Most (natural) redheads will have brown eyes, followed by hazel or green shades.
Previous studies had shown that redheads inherit two versions of the MC1R gene that leads to red hair – one from their mum and one from their dad. Although almost everyone with red hair has two copies of the red-haired version of MC1R, not everyone carrying two red-haired versions is a redhead.
Because it's a recessive trait, red hair can easily skip a generation. It can then reappear after skipping one or more generations if both parents, no matter their hair color, carry the red hair gene.
Contrary to what many people assume, redheads did not originate in Scandinavia, Scotland or Ireland, but in central Asia. Their coloring is due to a mutation in the MC1R gene that fails to produce sun-protective, skin-darkening eumelanin and instead causes pale skin, freckles and red hair.
